Abstract What we wanted to find out about is how rocket works, how a bottle rocket model relates to a real rocket, and what it feel like to see what a rocket looks like when it flies. This topic has gotten my group wondering how do rockets work for a while now and my team finds it interesting that rockets can fly and how they carry so much things with them. Before , we were looking up some research about rockets and how to build them. It is a hassle, but the end product is going to look really good. We shot the rockets into the air and after when we were done with all the researching and the building. We were going to then take down the results and do it for more than 5 times.One important procedure for this project was the amount of psi we put in the bottle rockets because if we didn’t get the correct psi than the rocket can't go up in the air longer. Second most important procedure was that to capture the rocket in the air because if we didn’t capture it then people will say that we didn’t do the project and we are lying. The last observation we need to catch was the amount of water we need to put in the beakers because they all need to be 500ml or else the rocket would go higher. What we concluded was that the 30-psi rockets went higher than the 15-psi rockets and that our hypotheses are all correct because we said that, “If we put more air pressure in the rockets then the rockets will stay in the air longer.” And it did.
STATEMENT OF PROBLEM
What is the effect of air pressure on in liter bottle rockets? (needs to include dependent variable- time)
Hypothesis
If we put more (more/less- choose one) air pressure in the rocket, then the rocket will stay in the air longer.
Independent variable - 15 psi and 30 psi
Dependent Variable - time the rocket is in the air
Controlled Variable - 500ml of water, Rocket
Materials (use bullets)
2 Bottles Rockets
Air compressor
Construction paper
Cardboard (cardboard isn't it?
Duct tape or Glue gun
Rocket Launcher
Safety Glasses
6 Beakers (1000ml)
Stop Watch
Procedure: 1. Make a bottle rocket:
Assemble a nosecone with graph paper (place a small bit of clay in the tip of the nosecone) (you didn't end up making this)
Use clear tape to fasten the nosecone to the bottom of the plastic bottle
Make fins out of cardboards (how many fins?)
Tape them on to the plastic bottle with duct tape one the sides of the top of the bottle
2.Fill the beakers up to 500ml with water 3.Pour it into each rocket (5) 4.Put the rockets on top of the rocket launcher 5.Plug the compressor to the rocket launcher 6.Hold the tip of the rocket launcher and the bottom of the rocket together 7.Press the air compressor button till it reaches 15 psi 8.Record the time of how long the rocket stayed in the air on the data table (Repeat steps 2-8 four more times & record on data table)
9. Repeat steps 2-8 but this time press the button till it reaches 30 psi
10.Record the time 5 times on the data table
Analysis
We measured the beakers to 1000ml of water, so we can put 500ml of water in each rocket. We used about 500ml of water for the rockets. We filled up the rocket with 500ml of water. We use the water to help shoot up the rocket in the air. To help shoot the rocket in the air, we use a air pressure level of 30 and 15 psi when we applied 15 psi it stayed in the air for 2.5 sec. We applied 30 psi to the rocket and it stayed in the air for 3 sec.
The air pressure was to shoot the rocket in the air. (<--- this paragraph describe the procedure- it would be better as the 3rd part of your abstract)
Analysis should be interpreting the data table and graph.
Conclusion (See page s27 for info on how to write a conclusion)
We thought if we apply more air pressure to the rocket it will stay in the air longer, but it turns out that the more water it has the higher it goes because the water pumps it up and causes it to go up. We compared the psi and it turns out that the more air you put inside the rocket the bottle pumps out the water faster once launched.(<--- this sentence can go in the analysis) I suggest that if you have more experience you will use more psi. Some of the rockets broke so next time we need to use duct tape better.
Purpose (use 3rd person) This lab is to help people learn about rockets and show how air pressure rockets work. People to know about rockets because rockets tell us if there is another universe. People find it interesting how air helps a rocket go into the sky and how fascinating it is. It depends on how much air pressure is applied to the rockets. If a lot of air pressure applied to the rocket, it will go up high. If little air pressure is applied it wont go that high. This matters because it causes the rocket to go higher and forces the.water to shoot out faster.
Rockets are use to go to place that air planes can not go. Rockets can go to other planet like Mars or Jupiter. Rockets carry satellites to space so they can be used as a communication device. Without rockets we would not know if there is another planet nor would we know if the Earth is round or not. (Why does this matter? Where else can this knowledge be applied?)
History (Who first studied rockets? When? Where? Who first studied water pressure? When? Where?)
The history of rockets has truly been fascinating to see and explore (<-- avoid opinions in a research report; delete). Rockets have been the most success of exploring and soaring through space. Rockets have been and still are the highest height that is explored in space. Rockets have also been in pieces. And each piece separate and take part and a role in a certain distance in space. Its like it has 2 containers that contains gas. The first person to ever study rockets was Sir Isaac Newton around the 17 century (<--explain this more; source?). (This paragraph has a lot of grammatical errors- read aloud & revise)
During the 1890s, a Russian schoolteacher named Konstantin Tsiolkovsky proposed the idea of putting water propellants in the rocket so it can achieve a greater distance when fired. He stated that speed and range of a rocket were only limiter by the exhaust of velocity of gas escaping. He is the father of modern astronautics. (source?)
Process (bold glossary terms; add a transition to 2nd paragraph to show how air pressure & rockets relate)
Air pressure rockets work by using air pressure. Air pressure is air that exerts really fast and with great mass. The weight of the air is the force that produces air pressure or atmospheric pressure. There is also water power rockets called fluid pressure (<--this doesnt make sense). Fluid pressure is all the forces exerted by the individual particles combined to make up the pressure exerted by the fluid. (source?)
Rockets work by moving upward when gases shooting out the back (bottom?) of the rocket push it in the opposite direction. (Explain action-reaction- newton's 3rd law! Cite textbook?) The reaction that causes the rocket is called the thrust. The more thrust, the more velocity the rocket gets. (Once in space, ) rockets must have a certain orbital velocity to roam around earth. Rockets need to have a escape velocity. Escape velocity is the velocity a rocket must reach to fly beyond a planet's gravitational pull. (description feels abrupt like information was left out or add transitions; source?)
Applications (interesting- explain more how air pressure could be used for car; cite sources) The idea of air powered rockets could also be use for cars (explain more). There would be less pollution in the world because everything is going to be air powered. A strong source of air will be enough to let a rocket in to space. (are there studies or trials being done? research)
Reflection
During our research, we found out there are many ways to test how long a rocket can stay up in the air. One of the ways was a water rocket. The most important part of it (specify) was the water and the rocket because without the rockets then we don't have the rockets than we cant do the experiment and if we don't have water than the rockets wont go up. We can put in how much water in the rockets, but the same amount we put in the rocket we have to put the same amount for the other rockets.
During our experiment, we wanted to test to see how long will the rocket will stay up in the air. We used two different psi, one was a 30 psi and the other was a 15 psi. The 30 psi went the longest because it had more pressure. The longest time the 30 psi went for was 4.2 seconds. The 15 psi didn't went for as long as the 30 psi cause it had half the psi as the 30. The 15 psi went for 2.9 seconds. What we thought about this project was that it was a fun project. We all did good and we probably might do this more often. I hope other people would do bottle rockets more often for their science fair project. (<-- data should be moved to analysis paragraph) What were your thoughts and feelings as you conducted the research.
